Testing in Create React App about sockette HOT 3 CLOSED

You can't run websocket libraries in NodeJS. This isn't a limitation of sockette but of NodeJS itself, it just doesn't provide the same WebSocket api as browsers.

You need to adjust your tests or your application to use a different or emulated code path depending on the environment it's in.

Something like this:

if (typeof WebSocket !== "undefined") {
   // Do real WebSocket stuff in the browser
} else {
   // We're in NodeJS, no WebSocket API!
}

What @ClickSimply said is correct. There's no WebSocket built-in within Node.js -- you have to either add the conditional check, or include a mock/stand-in for your tests.

You can use something like ws or uws as your Node.js version of WebSocket. Here's a usage example from the ws README.

Personally, I haven't tested Sockette extending from WebSocket replacement (since this is a browser module). But if I ever get around to writing tests for this library, I'd use either of those replacements to do so.

Hope that helps!
